Overview
The Hubbell Wiring Device-Kellems RCDP Daylight Sensor is a 24V DC indoor light-level measurement device engineered for commercial daylighting control systems. Operating on an open-loop control architecture, the RCDP continuously samples ambient daylight and transmits readings to a compatible room controller, enabling automated lighting adjustments that reduce energy consumption without disrupting occupant comfort. Its compact white plastic housing integrates discreetly into standard ceiling installations.
